SPACER FOR POSITION ADJUSTMENT AND REHABILITATION PIPELINE POSITION ADJUSTMENT METHOD WITH ITS USE THEREOF Russian patent published in 2019 - IPC F16L55/165 F16L55/18 

FIELD: pipelines.

SUBSTANCE: group of inventions relates to pipeline repair. Proposed brace comprises first and second wedge-like elements, each of which has skewed surface with one and same skew angle, and these bevelled surfaces are made with possibility of overlapping. On these skewed surfaces of the first and the second wedge-shaped elements fixing teeth are made, so that for the second wedge-shaped element it is possible to move relative to the first wedge-like element in direction of insertion of the spacer with increase of its general value in a stepwise manner, but possibility of its movement in reverse direction is excluded. One of the wedge-shaped elements, the first or the second one, in the areas equipped with fixing teeth, has elastically deformable element made with possibility of elastic deformation with provision for the first and the second wedge-shaped elements fixing teeth of possibility of disengagement and enabling the second wedge-shaped element to move in the reverse direction for repeated adjustment of the position of the rehabilitation pipe inside the existing pipe.

EFFECT: object of the proposed invention is a spacer installed in the space between the existing pipe and the rehabilitation pipe to adjust the position of the rehabilitation pipe inside the existing pipe.
